Clematisplant named &#39;VIVA POLONIA&#39;

ABSTRACT

A new and distinct  Clematis hybrid  named ‘VIVA POLONIA’ is disclosed, characterized by extremely floriferous, medium deep magenta colored flowers with distinctive white centers and tepal bases. Plants have a long blooming period and compact growth. The new cultivar is a  Clematis  typically suited for ornamental container and landscape use.

LATIN NAME OF THE GENUS AND SPECIES

Clematis hybrid

VARIETY DENOMINATION

‘VIVA POLONIA’

BACKGROUND OF THE INVENTION

The new Clematis cultivar is a product of a planned breeding program conducted by the inventor, Szczepan Marczynski, in Pruszkow, Poland. The objective of the breeding program was to produce new compact Clematis varieties with novel or new colors. The cross resulting in this new variety was made during 2004.

The seed parent is the unpatented variety, Clematis ‘Matka Siedliska’. The pollen parent is the unpatented variety, Clematis ‘Warszawska Nike’. The new variety was identified as a potentially interesting selection in 2006, at a greenhouse in Pruszkow, Poland.

Asexual reproduction of the new cultivar ‘VIVA POLONIA’ by vegetative tip cuttings was first performed during 2007, at a greenhouse in Pruszkow, Poland. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 8 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘VIVA POLONIA’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘VIVA POLONIA.’ These characteristics in combination distinguish ‘VIVA POLONIA’ as a new and distinct Clematis cultivar:

1. Extremely floriferous plants, with plants covered in flowers at maturity. 2. Medium sized flowers 3. Free flowering habit. 4. Compact plant growth, reaching 1.5 to 2 meters tall. 5. Long blooming period. 6. Flowers in a deep magenta red/claret color with attractive white shading and white tepal base.

PARENTAL COMPARISON

Plants of the new cultivar ‘VIVA POLONIA’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘VIVA POLONIA’ differ in the following:

1. Flowers are a deep red magenta color with white shading and white tepal base. The seed parent has white flowers with pink shading. 2. Single flower. The seed parent is single flower on new growth and double flower on previous year's growth. 3. Smaller flowers than seed parent.

Plants of the new cultivar ‘VIVA POLONIA’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘VIVA POLONIA’ differ in the following;

1. Flowers in a deep red magenta color with white shading and white base. The pollen parent has solid purple-violet flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘VIVA POLONIA’ can be compared to the known commercial variety Clematis hybrid ‘Solidarnosc’, unpatented. The Clematis varieties have similar flower color and produce similar amounts of tepals. ‘VIVA POLONIA’ differs from ‘Solidarnosc’ in the following:

1. Flowers in a deep magenta red/claret color with white shading and white tepal base.

-   -   The comparator has solid red flowers with occasional faint,         light pink streaking.

2. Heart shaped tepals. The comparator has elliptic shaped tepals.

3. More floriferous than comparator.

Plants of the new cultivar ‘VIVA POLONIA’ can be compared to the known commercial variety Clematis ‘Sweet Summer Love’ U.S. Plant Pat. No. 24,044. The Clematis varieties have similar flower color and produce similar amounts of tepals. ‘VIVA POLONIA’ differs from the comparator in the following:

1. Six to eight tepals. The comparator has 4 tepals

2. Larger flower size.

3. Flower color is near RHS Red-purple 71A. The comparator flower color is near RHS Red-purple 61A.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical flowers and foliage of ‘VIVA POLONIA’ grown outdoors in Pruszkow, Poland. This plant is approximately 3 years old, grown outdoors. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
